really confused about printing registration address for k1

[scottamus 0]

How can I print registration address confirmation that they wanted from us to bring it in the interview for k1 visa?

When you press new schedule on lift of ustraveldocs.com it gives you three options

Iv registration address

Immigrant visa

Non immigrant visa

From immigrant visa we will be able to schedule when consular section upload the case on the site

We will get ( The confirmation of address of registration) from the first option

Iv registration address

What makes me puzzle :

That under ( Iv registration address option) there is no class k1 visa to select it from other different classes of visa??

When you have this answer , please tell me
